Privacy

The free sample needs no account and no email address.

• Your answers and progress are stored in your own browser (local storage) and are not sent to our servers. Clearing the site data removes them; the practice exam also has a button for it.
• Account cookie. The site sets one cookie that identifies an anonymous account, so that a purchase applies to your browser. It is not used for advertising.
• Payment is handled by Stripe on its own checkout page. We do not see or store card details. The email address entered at checkout is used only to send a sign-in link when you open the site on another device.
• Visit statistics. Visits and button clicks are counted with a self-hosted analytics service that sets no cookies and does not follow you across sites.
• Fonts. The IBM Plex Sans font is loaded from Google Fonts, which receives your IP address with the request.
• Error reports. If you use Report an error, we receive the text and any email address you choose to add.
